The invention relates to a process for preparing mixtures of enantiomers of PPI~s proton pump inhibitors having a sulphinyl structure, i.e. Pyridine-2- ylmethylsulfinyl-1H-benzimidazoles, using a mixture of enantiomers of chiral zirconium complexes or chiral hafnium complexes.
L'invention concerne un procédé permettant de préparer des mélanges d'énantiomères d'inhibiteurs de la pompe à protons (IPP), présentant une structure sufinyle, à savoir des Pyridin-2-yl-méthy-lsulfinyl-1H-benzimidazoles, à partir d'un mélange d'énantiomères de complexes chiraux de zirconium ou de complexes chiraux de hafnium.
